To start the cold engine it's necessary to inject fuel into the cylinder, to do this, squeeze the pump only
once while holding the accelerator completely open until you hear the fuel squirt from the carburetor into
the cylinder.
OPEN the fuel
tank vent cock
in this position:
Fig. 22 – Fuel primer push
diaphragm
Push the carburetor diaphragm while pump the fuel as
in fig. 22 for to fuel primer before start the engine.
Allow a certain quantity of fuel to enter the carburetor but not enough to allow it to go out of the air
filter, if this happens, this means that the engine could be flooded and will hesitate to start .
There are three different positions that can be used to start the engine. These positions are:
•
•
•
•
Standing in front of the unit, holding the unit on the ground.
•
•
•
•
Strapped into the unit, standing on the ground
•
•
•
•
In flight.
We’ll cover each of these starting options in turn.
- Standing in front of the unit, holding the unit on the ground
WARNING!
The method of holding the throttle handle is important in this position.
Hold the throttle handle such that you can easily reach the stop button, but not so that you can
inadvertently squeeze the throttle (do not strap your hand to throttle at this point).
A common accident can happen where you hold the throttle in the same hand that you hold the motor
unit, and if you squeeze the throttle a little, the thrust of the machine will push the throttle onto your
hand, causing you to squeeze the throttle even more.
Make sure that you CANNOT inadvertently squeeze the throttle handle when starting in this position.
-
Stand in front of the unit, and place your left hand on the top of the central frame tube. Hold the
throttle handgrip in the same left hand
-
Grasp the manual start grip with the other hand and pull it until the engine starts. The engine should
start after a few propeller turns.
3.4 The fuel system
The fuel system consists of the fuel tank, lines, manual pump, and carburator.
When starting engine cold, the carburator must be primed, this is simply done by pressing the
diaphragm of the carburator while squeezing the hand pump.
This forces fuel to travel from the tank to the carburator float chamber.
As soon as you hear the fuel reach the carburator stop squeezing the pump so as not to flood the
system.
